|Title:||POWER SOURCE SYSTEM|
In order to control output from a first and a second DC power source, two inflection points, specifically a maximum point and a minimum point, are provided, by ON-OFF control of switching elements (S1-S5, S5a, S5b), in a first reactor current (IL1) and a second reactor current (IL2) in one control period. In at least some of the inflection points of the first and second reactor currents (IL1, IL2), the switching elements to be turned ON or OFF simultaneously are controlled so as to turn ON or OFF in a prescribed order with a time difference applied. At the inflection points to which a time difference has been applied, switching loss occurs in switching elements turned OFF later or in switching elements turned ON earlier, in accordance with the prescribed order.
